DETAILED DESCRIPTION

Before the present technology is disclosed and described, it is to beunderstood that this technology is not limited to the particularstructures, process actions, or materials disclosed herein, but isextended to equivalents thereof as would be recognized by thoseordinarily skilled in the relevant arts. It should also be understoodthat terminology employed herein is used for the purpose of describingparticular examples only and is not intended to be limiting.

EXAMPLE EMBODIMENTS

An initial overview of technology embodiments is provided below and thenspecific technology embodiments are described in further detail later.This initial summary is intended to aid readers in understanding thetechnology more quickly but is not intended to identify key features oressential features of the technology nor is it intended to limit thescope of the claimed subject matter.

Mobile communication has evolved significantly from early voice systemsto today's highly sophisticated integrated communication platform. Thenext generation wireless communication system, 5G, or new radio (NR)will provide access to information and sharing of data anywhere, andanytime by various users and applications. NR is expected to be aunified network/system that targets to meet vastly different andsometime conflicting performance dimensions and services. Such diversemulti-dimensional designs are driven by different services andapplications. In general, NR will evolve based on 3GPP LTE-Advanced withadditional potential new Radio Access Technologies (RATs) to enrichpeople lives with better, simple and seamless wireless connectivitysolutions. NR will enable everything to be connected by wireless systemsand deliver fast, rich contents and services.

For 5G systems, high frequency band communication has attractedsignificantly attention from the industry, due to the fact that it canprovide wider bandwidth to support future integrated communicationsystems. Accordingly, beamforming is a critical technology for theimplementation of high frequency band systems due to the fact that thebeamforming gain can compensate the severe path loss caused byatmospheric attenuation, improve the signal to noise ratio (SNR), andenlarge the coverage area. By aligning the transmission beam to thetarget UE, the radiated energy is focused for higher energy efficiency,and the mutual UE interference is suppressed.

FIG. 1 illustrates an example of a simultaneous transmission usingmultiple Transmission/Reception (Tx/Rx) beams. FIG. 1 furtherillustrates one example of simultaneous transmission using Tx and Rxbeams. In the example, the UE is equipped with two or multiple antennasub-arrays, also referred to as antenna panels. Each antenna sub-arraycan be used to transmit and receive a signal in a directed beam with atransmission-reception point (TRP). A TRP is synonymous with a basestation (BS) or next generation node B (gNB). The use of multiplesub-arrays or panels allows simultaneous transmission and receptionusing multiple beams to be supported at a UE.

For the multiple transmitting antenna case, the phase between differentantennas can be discontinuous, hence it may be difficult to employ anantenna combination based scheme. Accordingly, an antenna selectionbased transmission scheme can be considered for the transmission ofphysical uplink control channel (PUCCH). As mentioned above, the UE maybe equipped with multiple panels. In this case, certain mechanisms canbe defined to select the panel(s) to transmit the PUCCH.

FIG. 2(a) illustrates an example of a new radio (NR) physical uplinkcontrol channel (PUCCH) with a short duration in an uplink (UL) dataslot. For NR PUCCH with short duration, NR PUCCH and physical uplinkshared channel (PUSCH) are multiplexed in a time division multiplexing(TDM) manner, which can be targeted for low latency application. For theUL data slot, NR PUCCH and PUSCH can be multiplexed in a frequencydivision multiplexing (FDM) fashion. Additionally, in order toaccommodate the DL to UL and UL to DL switching time and round-trippropagation delay, a guard period (GP) is inserted between the NRphysical downlink control channel (NR PDCCH) and NR physical uplinkshared channel (NR PUSCH) or NR physical uplink control channel (NRPUCCH) in the case when NR PUSCH and NR PUCCH are multiplexed in the FDMmanner.

FIG. 2(b) illustrates an example of a new radio (NR) physical uplinkcontrol channel (PUCCH) with a long duration in an uplink (UL) dataslot. For NR PUCCH with long duration, multiple OFDM symbols can beallocated for NR PUCCH to improve link budget and uplink coverage forthe control channel. For the UL data slot, NR PUCCH and PUSCH can bemultiplexed in a frequency division multiplexing (FDM) fashion.Additionally, in order to accommodate the DL to UL and UL to DLswitching time and round-trip propagation delay, a guard period (GP) isinserted between the NR physical downlink control channel (NR PDCCH) andNR physical uplink shared channel (NR PUSCH) or NR physical uplinkcontrol channel (NR PUCCH) in the case when NR PUSCH and NR PUCCH aremultiplexed in the FDM manner.

In some embodiments for NR, short and long PUCCH can be used to carryuplink control information (UCI). Further, the UCI may include ascheduling request (SR), a hybrid automatic repeatrequest-acknowledgement (HARQ-ACK) feedback, a channel state information(CSI) report, e.g., channel quality indicator (CQI), a pre-coding matrixindicator (PMI), a CSI resource indicator (CRI) and a rank indicator(RI) and/or beam related information, such as reference signal receivedpower (RSRP) information via layer one. (e.g., L1-RSRP).

Control Signal for Antenna Selection

As the phase can be discontinuous for different antenna ports, theantenna selection can be considered for the transmission of the PUCCH.The gNB can configure the PUCCH with a selection of which antenna portshould be used for transmission of the PUCCH.

In one embodiment of the invention, an antenna port (AP) index for thetransmission of PUCCH can be explicitly indicated in the downlinkcontrol information (DCI) or configured by higher layers via radioresource control (RRC) signaling or the medium access layer-controlelement (MAC-CE) or a combination thereof.

This may also depend on a specific UCI type. In one option, for theperiodic CSI report and/or scheduling request (SR), the AP index for thetransmission of PUCCH can be configured by higher layers. Additionally,the aperiodic CSI report which may be carried by the physical uplinkshared channel (PUSCH), the AP configuration and/or SRS resourceindicator (SRI) for the transmission of PUSCH, can be configured by RRCsignaling or indicated in the DCI or a combination thereof. In oneexample, the AP index used for the transmission of the PUSCH carryingaperiodic CSI report can be configured by higher layer while SRI can beindicated in the DCI.

Further, there can be a configuration for a semi-persistence scheduling(SPS) CSI report, an AP index or an SRS resource indicator (SRI) for thetransmission of PUSCH, or any combination to be configured by RRCsignaling, MAC-CE, indicated in the DCI, or a combination thereof.

In addition, for a PUCCH carrying HARQ-ACK feedback, an AP index and/orSRI for the transmission of PUCCH can be configured by higher layers orexplicitly indicated in the DCI or a combination thereof. In oneexample, the AP index used for the transmission can be explicitlyindicated in the DCI. More specifically, assuming that the UE cantransmit the PUCCH with 2 APs, a 2 bit indicator can be used to indicatewhich AP or a combination of APs are used for the transmission of PUCCH,as illustrated in Table 1. In one embodiment, the 2 bit indicator can besent in the DCI.

TABLE 1 An example for antenna port indication for PUCCH transmissionPUCCH AP Bit field PUCCH AP 00 AP #0 01 AP #1 10 AP#0 and #1 withPrecoder #0 11 AP#0 and #1 with Precoder #1

In the table, precoder #0 or #1 can be predefined in the specificationor configured by the higher layer via NR minimum system information(MSI), NR remaining minimum system information (RMSI), NR other systeminformation (OSI) or radio resource control (RRC) signaling.

Alternatively, in the case where there is beam correspondence, animplicit beam association can be used, i.e., an Rx beam can be used forthe reception of the physical downlink shared channel (PDSCH) and canfurther be employed as the Tx beam for the transmission of the PUCCHcarrying the HARQ-ACK feedback.

In another embodiment of the invention, the Cyclic Redundant Check (CRC)code of the Downlink Control Information (DCI) can be masked with acodeword representing the transmitting antenna port(s) index of thePUCCH carrying the HARQ-ACK feedback. Table 2 illustrates one example ofan antenna selection mask for PUCCH transmission.

Note that a sub-set of Table 2 can be used, which can be pre-defined orconfigured by higher layer signaling, indicated in the DCI, or acombination thereof, and/or determined based on the UE capability. Also,a different set of antenna selection masks from Table 2 can be adoptedas well. For example, the antenna selection mask for each of the portindexes can be chosen to have a large hamming distance between the masksas illustrated in Table 3 below.

TABLE 3 An example for antenna selection mask for PUCCH transmissionSelected port index Antenna selection mask 0 0, 0, 0, 0, 0, 0, 0, 0, 0,0, 0, 0, 0, 0, 0, 0 1 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1 20, 1, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0 3 1, 0, 1, 0, 1, 0, 1, 0,0, 1, 0, 1, 0, 1, 0, 1 0, 1 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1,0 2, 3 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 1

Each of the 16 bits, in Table 2 and Table 3, in the antenna selectionmask are configured to indicate which antenna to transmit or receivefrom. For example, UE transmit antenna 0 is indicated using the mask0000 0000 0000 0000, and antenna 1 is indicated using the mask 1000 00000000 0000. The receiver uses blind decoding to determine which mask wasused, and, therefore, which antenna to transmit from

In another embodiment, during initial access, the next generation node B(gNB) may not know the number of antenna ports for a UE. In one option,the UE can determine the antenna port(s) used to transmit the PUCCH byitself without necessarily relying on other information orconfiguration. In another option, the UE may use the same antennaport(s) for PUCCH transmission as are used for the physicalrandom-access channel (PRACH) transmission.

In another embodiment of the invention, prior to the RRC configurationor during the initial access, when the UE transmits the UL signalincluding PUSCH in Message (Msg.) 3 and the PUCCH carrying HARQ-ACK forcorresponding Msg. 4 transmission, the UE can assume the same AP or beamassociation is being utilized with the PRACH transmission.

In another embodiment, antenna port cycling can be used for the PUCCHtransmission. Different antenna port(s) can be used in a differentfrequency and/or time resource of PUCCH, which can help in achievingdiversity gain. If the antenna port(s) belong to one panel (antennaports sub-set), the same open-loop and closed-loop power control can beapplied; otherwise, different power control loops may be applied.

QCL Assumption Between SRS and PUCCH

In one embodiment of the invention, for the gNB to finish a linkadaptation, e.g. to identify which antenna port(s) should be better, thePUCCH and some SRS resources can be Quasi Co-Located (QCLed) with otherparameters such as an average gain, a delay spread, a Doppler spread, aDoppler shift, one or more average delay parameters, and one or morespatial Rx parameters. Additionally, the SRS resource can be dividedinto 3 groups in one embodiment. In the first group, there can be an SRSresource for beam management. In the second group, there can be an SRSresource for PUSCH transmission. In the second group, there can be anSRS resource for PUCCH transmission.

FIG. 3 illustrates an example for a sounding reference signal (SRS)resource group partition. Further in FIG. 3, there can be SRS resourcegrouping, where there can be some part of a group overlap between anycombination of group 1, group 2 and group 3, i.e., SRS resource 6. Inthis example, SRS resource 6 can be included in both group 2 and group3. SRS resource 6 is configured for two SRS resource groups, enablingfunctionality for both groups. In one embodiment, group 2 can be usedfor a PUSCH beam indication and group 3 can be used for PUCCH beamindication, resulting in SRS resource 6 being enabled for both PUSCH andPUCCH beam indication.

In some embodiments, the selection of which SRS resource, or combinationthereof, that is used, for PUCCH/PUSCH/beam management can bepre-defined or configured by higher layer signaling.

In one embodiment, the determination of which SRS resource(s) that canbe QCLed with PUCCH, can be pre-defined or configured by higher layersignaling or DCI. In an example, one or multiple SRS resource Index(SRI) can be indicated by the DCI, the MAC Control Element (CE), RRCsignaling or a combination thereof. In one example, as mentioned above,more than one SRI which are QCLed with PUCCH transmission, can beconfigured by higher layers via RRC signaling, where one SRI can bedynamically indicated in the DCI for PUCCH transmission.

Sequence Search Summary

Computer generated sequences have been determined for 4-PSK and 8-PSKmodulation types.

Both the 4-PSK and the 8-PSK modulated symbols can be written in thefollowing form in the frequency domain:r(n)=e ^(jφ(n)π/4),0≤n<M _(sc) ^(RS),where M_(sc) ^(RS)-sequence length and φ(n) is selected from thefollowing set Φ:

$\Phi = \left\{ \begin{matrix}{\left\lbrack {{- 3},{- 1},1,3} \right\rbrack,{4 - {{PSK}\mspace{14mu}{Modulation}}}} \\{\left\lbrack {{- 3},{- 2},{- 1},0,1,2,3,4} \right\rbrack,{8 - {{PSK}\mspace{14mu}{Modulation}}}} \\{{\left\lbrack {{- 5},{- 4},{- 3},{- 2},{- 1},0,1,2,3,4,5,6} \right\rbrack*{2/3}},{12 - {{PSK}\mspace{14mu}{Modulation}}}} \\{{\left\lbrack {{- 7},{- 6},{- 5},{- 4},{- 3},{- 2},{- 1},0,1,2,3,4,5,6,7,8} \right\rbrack/2},{16 - {{PSK}\mspace{14mu}{Modulation}}}} \\{{\left\lbrack {{- 11},{- 10},{- 9},{- 8},{- 7},{- 6},{- 5},{- 4},{- 3},{- 2},{- 1},0,1,2,3,4,5,6,7,8,9,10,11,12} \right\rbrack/3},{24 - {{PSK}\mspace{14mu}{Modulation}}}}\end{matrix} \right.$

Through these equations in the frequency domain, 30 base demodulationreference symbol (DMRS) sequences can be configured. Each base sequenceis used to generate 12 cyclically shifted sequences to form an extendedset of DMRS signals, via the following equation:r _(sc) ^((α))(n)=(n)e ^(jαn) r(n),0≤n<M _(sc) ^(RS)

To generate the 12 cyclically shifted sequences, the value of parameterα can be taken from the set:

$\frac{k\;\pi}{6},$where k is equal to an integer between 0 to 11.

In one embodiment, a whole set of 360 sequences with a lowPeak-to-Average Power Ratio (PAPR), a configuration management (CM) andlow mutual cross-correlation properties can be found. In addition, goodcross-correlation properties with an LTE sequence set can be determined,comprising one or more of the low PAPR, the CM and the low mutualcross-correlation properties.

In order to find 30 base sequences, satisfying good PAPR/CM/mutualcorrelation and mutual cross-correlation properties, several candidatesets of base sequences has been identified.

In one embodiment, only 30 base sequences are specified for eachcandidate sequence set. Additional sequence sets with identicalproperties could be obtained with common phase rotation applied to allsequences from the candidate set simultaneously. Additional sequencesets can further be obtained in instances where a cyclic shift with anyvalue α, selected from the range

${\alpha = \left\lbrack {\frac{\pi}{2};\pi;\frac{3\pi}{2};{2\pi}} \right\rbrack},$and multiples of any elements are applied to all sequences fromcandidate sets simultaneously.4-PSK Candidate Sets

Through the above configurations and embodiments, several 4-PSK sequenceset candidates were found. FIG. 4 illustrates an exemplary tableillustrating the selected 4 phase shift key (PSK) sequence set candidateparameters.

The disclosed 4PSK based PUCCH DMRS base sequences illustrate theimproved advantages of PAPR/CM and mutual cross-correlation performancerelative to the legacy LTE PUCCH DMRS sequences. In addition, thedisclosed sequences have low cross-correlation properties compared tothe legacy LTE PUCCH DMRS sequences. Further examples of improvedperformance are described below in reference to 8PSK based PUCCH DMRSsequences.

8-PSK Candidate Set

The properties of the 8-PSK sequence set candidates are provided in FIG.16. FIG. 16 illustrates an exemplary table illustrating selected 8-PSKSequence Set Candidate Parameters. For performance comparison, theproperties of 1PRB LTE PUCCH sequences are also provided. The φ(n)values for the selected sequence sets are provided in FIG. 17-FIG. 20,where each of the figures illustrate exemplary tables illustratingdefinitions of ϕ(n) for M_(sc) ^(RS)=12 for 8-PSK. FIG. 17 illustratesan exemplary table illustrating definitions of ϕ(n) for M_(sc) ^(RS)=12for 8-PSK sequence set candidates in sequence set #1, based on thelimitations illustrated in FIG. 16 for sequence set #1. FIG. 18illustrates an exemplary table illustrating definitions of ϕ(n) forM_(sc) ^(RS)=12 for 8-PSK sequence set candidates in sequence set #2,based on the limitations illustrated in FIG. 16 for sequence set #2.FIG. 19 illustrates an exemplary table illustrating definitions of ϕ(n)for M_(sc) ^(RS)=12 for 8-PSK sequence set candidates in sequence set#3, based on the limitations illustrated in FIG. 16 for sequence set #3.FIG. 20 illustrates an exemplary table illustrating definitions of ϕ(n)for M_(sc) ^(RS)=12 for 8-PSK sequence set candidates in sequence set#4, based on the limitations illustrated in FIG. 16 for sequence set #4.

Based on an analysis of the 8-PSK candidate sets, we can see that theproposed sequences have improved properties compared to the QPSK/4PSKbased sequences and can be used as a candidates for the NR PUCCH DMRSgeneration. Further, a subset of the sequences selected from the tablescan work for NR PUCCH DMRS can be utilized as well.

In some embodiments, 12-PSK or 24-PSK alphabet symbols can be definedand used for PUCCH DMRS base sequences. These configurations can furtherreduce PAPR, CM statistics of the sets; improve cross-correlationproperties within the set, and also within the set of LTE PUCCH basesequences, as well as their cyclic shifted version.

Configurability of Base Sequences for NR PUCCH DMRS Among LTE and NRSequences

In addition to new base sequences for NR PUCCH, LTE PUCCH DMRS sequencescan be employed for use for the NR PUCCH. For example, for 1 PRB NRPUCCH sequence, the sequences generated using phases sets from FIG. 21may be used. FIG. 21 illustrates an exemplary table illustrating LTESets of ϕ(n) for M_(sc) ^(RS)=12.

In one embodiment, the configured set of NR PUCCH DMRS sequences for aUE, can be partially overlapped with the LTE PUCCH DMRS sequence set orcan be an independent set of sequences by employing only the new basesequences designed for NR PUCCH. Additionally, LTE PUCCH DMRS sequenceswithout the new base sequences can be configured for NR PUCCH. Anexample of this could be configurable in NR-LTE co-existence scenarios.

In one embodiment, the set of sequences employed for NR PUCCH DMRS canbe configured or signaled to the UEs by a physical broadcast channel(PBCH), one or more system information blocks (SIBs), a remaining systeminformation signaling (RMSI), a cell common or UE specific radioresource control (RRC) signaling. Alternatively, in cases where dynamicswitching between the NR specific new base sequences and LTE PUCCHsequences is desired, L1 or MAC CE (Control Element) based signaling canbe configured.

FIG. 27 illustrates architecture of a system 2700 of a network inaccordance with some embodiments. The system 2700 is shown to include auser equipment (UE) 2701 and a UE 2702. The UEs 2701 and 2702 areillustrated as smartphones (e.g., handheld touchscreen mobile computingdevices connectable to one or more cellular networks), but may alsocomprise any mobile or non-mobile computing device, such as PersonalData Assistants (PDAs), pagers, laptop computers, desktop computers,wireless handsets, or any computing device including a wirelesscommunications interface.

In some embodiments, any of the UEs 2701 and 2702 can comprise anInternet of Things (IoT) UE, which can comprise a network access layerdesigned for low-power IoT applications utilizing short-lived UEconnections. An IoT UE can utilize technologies such asmachine-to-machine (M2M) or machine-type communications (MTC) forexchanging data with an MTC server or device via a public land mobilenetwork (PLMN), Proximity-Based Service (ProSe) or device-to-device(D2D) communication, sensor networks, or IoT networks. The M2M or MTCexchange of data may be a machine-initiated exchange of data. An IoTnetwork describes interconnecting IoT UEs, which may include uniquelyidentifiable embedded computing devices (within the Internetinfrastructure), with short-lived connections. The IoT UEs may executebackground applications (e.g., keep-alive messages, status updates,etc.) to facilitate the connections of the IoT network.

The UEs 2701 and 2702 may be configured to connect, e.g.,communicatively couple, with a radio access network (RAN) 2710—the RAN2710 may be, for example, an Evolved Universal Mobile TelecommunicationsSystem (UMTS) Terrestrial Radio Access Network (E-UTRAN), a Ne8Gen RAN(NG RAN), or some other type of RAN. The UEs 2701 and 2702 utilizeconnections 2703 and 2704, respectively, each of which comprises aphysical communications interface or layer (discussed in further detailbelow); in this example, the connections 2703 and 2704 are illustratedas an air interface to enable communicative coupling, and can beconsistent with cellular communications protocols, such as a GlobalSystem for Mobile Communications (GSM) protocol, a code-divisionmultiple access (CDMA) network protocol, a Push-to-Talk (PTT) protocol,a PTT over Cellular (POC) protocol, a Universal MobileTelecommunications System (UMTS) protocol, a 3GPP Long Term Evolution(LTE) protocol, a fifth generation (5G) protocol, a New Radio (NR)protocol, and the like.

In this embodiment, the UEs 2701 and 2702 may further directly exchangecommunication data via a ProSe interface 2705. The ProSe interface 2705may alternatively be referred to as a sidelink interface comprising oneor more logical channels, including but not limited to a PhysicalSidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel(PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a PhysicalSidelink Broadcast Channel (PSBCH).

The UE 2702 is shown to be configured to access an access point (AP)2706 via connection 2707. The connection 2707 can comprise a localwireless connection, such as a connection consistent with any IEEE802.11 protocol, wherein the AP 2706 would comprise a wireless fidelity(WiFi®) router. In this example, the AP 2706 is shown to be connected tothe Internet without connecting to the core network of the wirelesssystem (described in further detail below).

The RAN 2710 can include one or more access nodes that enable theconnections 2703 and 2704. These access nodes (ANs) can be referred toas base stations (BSs), NodeBs, evolved NodeBs (eNBs), next GenerationNodeBs (gNB), RAN nodes, and so forth, and can comprise ground stations(e.g., terrestrial access points) or satellite stations providingcoverage within a geographic area (e.g., a cell). The RAN 2710 mayinclude one or more RAN nodes for providing macrocells, e.g., macro RANnode 2711, and one or more RAN nodes for providing femtocells orpicocells (e.g., cells having smaller coverage areas, smaller usercapacity, or higher bandwidth compared to macrocells), e.g., low power(LP) RAN node 2712.

Any of the RAN nodes 2711 and 2712 can terminate the air interfaceprotocol and can be the first point of contact for the UEs 2701 and2702. In some embodiments, any of the RAN nodes 2711 and 2712 canfulfill various logical functions for the RAN 2710 including, but notlimited to, radio network controller (RNC) functions such as radiobearer management, uplink and downlink dynamic radio resource managementand data packet scheduling, and mobility management.

In accordance with some embodiments, the UEs 2701 and 2702 can beconfigured to communicate using Orthogonal Frequency-DivisionMultiplexing (OFDM) communication signals with each other or with any ofthe RAN nodes 2711 and 2712 over a multicarrier communication channel inaccordance various communication techniques, such as, but not limitedto, an Orthogonal Frequency-Division Multiple Access (OFDMA)communication technique (e.g., for downlink communications) or a SingleCarrier Frequency Division Multiple Access (SC-FDMA) communicationtechnique (e.g., for uplink and ProSe or sidelink communications),although the scope of the embodiments is not limited in this respect.The OFDM signals can comprise a plurality of orthogonal subcarriers.

In some embodiments, a downlink resource grid can be used for downlinktransmissions from any of the RAN nodes 2711 and 2712 to the UEs 2701and 2702, while uplink transmissions can utilize similar techniques. Thegrid can be a time-frequency grid, called a resource grid ortime-frequency resource grid, which is the physical resource in thedownlink in each slot. Such a time-frequency plane representation is acommon practice for OFDM systems, which makes it intuitive for radioresource allocation. Each column and each row of the resource gridcorresponds to one OFDM symbol and one OFDM subcarrier, respectively.The duration of the resource grid in the time domain corresponds to oneslot in a radio frame. The smallest time-frequency unit in a resourcegrid is denoted as a resource element. Each resource grid comprises anumber of resource blocks, which describe the mapping of certainphysical channels to resource elements. Each resource block comprises acollection of resource elements; in the frequency domain, this mayrepresent the smallest quantity of resources that currently can beallocated. There are several different physical downlink channels thatare conveyed using such resource blocks.

The physical downlink shared channel (PDSCH) may carry user data andhigher-layer signaling to the UEs 2701 and 2702. The physical downlinkcontrol channel (PDCCH) may carry information about the transport formatand resource allocations related to the PDSCH channel, among otherthings. It may also inform the UEs 2701 and 2702 about the transportformat, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request)information related to the uplink shared channel. Typically, downlinkscheduling (assigning control and shared channel resource blocks to theUE 102 within a cell) may be performed at any of the RAN nodes 2711 and2712 based on channel quality information fed back from any of the UEs2701 and 2702. The downlink resource assignment information may be senton the PDCCH used for (e.g., assigned to) each of the UEs 2701 and 2702.

The PDCCH may use control channel elements (CCEs) to convey the controlinformation. Before being mapped to resource elements, the PDCCHcomplex-valued symbols may first be organized into quadruplets, whichmay then be permuted using a sub-block interleaver for rate matching.Each PDCCH may be transmitted using one or more of these CCEs, whereeach CCE may correspond to nine sets of four physical resource elementsknown as resource element groups (REGs). Four Quadrature Phase ShiftKeying (QPSK) symbols may be mapped to each REG. The PDCCH can betransmitted using one or more CCEs, depending on the size of thedownlink control information (DCI) and the channel condition. There canbe four or more different PDCCH formats defined in LTE with differentnumbers of CCEs (e.g., aggregation level, L=1, 2, 4, or 8).

Some embodiments may use concepts for resource allocation for controlchannel information that are an e8ension of the above-describedconcepts. For example, some embodiments may utilize an enhanced physicaldownlink control channel (EPDCCH) that uses PDSCH resources for controlinformation transmission. The EPDCCH may be transmitted using one ormore enhanced the control channel elements (ECCEs). Similar to above,each ECCE may correspond to nine sets of four physical resource elementsknown as an enhanced resource element groups (EREGs). An ECCE may haveother numbers of EREGs in some situations.

The RAN 2710 is shown to be communicatively coupled to a core network(CN) 2720—via an S1 interface 2713. In embodiments, the CN 2720 may bean evolved packet core (EPC) network, a Next Gen Packet Core (NPC)network, or some other type of CN. In this embodiment the S1 interface2713 is split into two parts: the S1-U interface 2714, which carriestraffic data between the RAN nodes 2711 and 2712 and the serving gateway(S-GW) 2722, and the S1-mobility management entity (MME) interface 2715,which is a signaling interface between the RAN nodes 2711 and 2712 andMMEs 2721.

In this embodiment, the CN 2720 comprises the MMEs 2721, the S-GW 2722,the Packet Data Network (PDN) Gateway (P-GW) 2723, and a home subscriberserver (HSS) 2724. The MMEs 2721 may be similar in function to thecontrol plane of legacy Serving General Packet Radio Service (GPRS)Support Nodes (SGSN). The MMEs 2721 may manage mobility aspects inaccess such as gateway selection and tracking area list management. TheHSS 2724 may comprise a database for network users, includingsubscription-related information to support the network entities'handling of communication sessions. The CN 2720 may comprise one orseveral HSSs 2724, depending on the number of mobile subscribers, on thecapacity of the equipment, on the organization of the network, etc. Forexample, the HSS 2724 can provide support for routing/roaming,authentication, authorization, naming/addressing resolution, locationdependencies, etc.

The S-GW 2722 may terminate the S1 interface 2713 towards the RAN 2710,and routes data packets between the RAN 2710 and the CN 2720. Inaddition, the S-GW 2722 may be a local mobility anchor point forinter-RAN node handovers and also may provide an anchor for inter-3GPPmobility. Other responsibilities may include lawful intercept, charging,and some policy enforcement.

The P-GW 2723 may terminate an SGi interface toward a PDN. The P-GW 2723may route data packets between the EPC network 2723 and externalnetworks such as a network including the application server 2730(alternatively referred to as application function (AF)) via an InternetProtocol (IP) interface 2725. Generally, the application server 2730 maybe an element offering applications that use IP bearer resources withthe core network (e.g., UMTS Packet Services (PS) domain, LTE PS dataservices, etc.). In this embodiment, the P-GW 2723 is shown to becommunicatively coupled to an application server 2730 via an IPcommunications interface 2725. The application server 2730 can also beconfigured to support one or more communication services (e.g.,Voice-over-Internet Protocol (VoIP) sessions, PTT sessions, groupcommunication sessions, social networking services, etc.) for the UEs2701 and 2702 via the CN 2720.

The P-GW 2723 may further be a node for policy enforcement and chargingdata collection. Policy and Charging Enforcement Function (PCRF) 2726 isthe policy and charging control element of the CN 2720. In a non-roamingscenario, there may be a single PCRF in the Home Public Land MobileNetwork (HPLMN) associated with a UE's Internet Protocol ConnectivityAccess Network (IP-CAN) session. In a roaming scenario with localbreakout of traffic, there may be two PCRFs associated with a UE'sIP-CAN session: a Home PCRF (H-PCRF) within a HPLMN and a Visited PCRF(V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF2726 may be communicatively coupled to the application server 2730 viathe P-GW 2723. The application server 2730 may signal the PCRF 2726 toindicate a new service flow and select the appropriate Quality ofService (QoS) and charging parameters. The PCRF 2726 may provision thisrule into a Policy and Charging Enforcement Function (PCEF) (not shown)with the appropriate traffic flow template (TFT) and QoS class ofidentifier (QCI), which commences the QoS and charging as specified bythe application server 2730.

In some embodiments, the PMC 2812 may manage power provided to thebaseband circuitry 2804. In particular, the PMC 2812 may controlpower-source selection, voltage scaling, battery charging, or DC-to-DCconversion. The PMC 2812 may often be included when the device 2800 iscapable of being powered by a battery, for example, when the device isincluded in a UE. The PMC 2812 may increase the power conversionefficiency while providing desirable implementation size and heatdissipation characteristics.

While FIG. 28 shows the PMC 2812 coupled only with the basebandcircuitry 2804. However, in other embodiments, the PMC 2812 may beadditionally or alternatively coupled with, and perform similar powermanagement operations for, other components such as, but not limited to,application circuitry 1602, RF circuitry 2806, or FEM 2808.

In some embodiments, the PMC 2812 may control, or otherwise be part of,various power saving mechanisms of the device 2800. For example, if thedevice 2800 is in an RRC_Connected state, where it is still connected tothe RAN node as it expects to receive traffic shortly, then it may entera state known as Discontinuous Reception Mode (DRX) after a period ofinactivity. During this state, the device 2800 may power down for briefintervals of time and thus save power.

If there is no data traffic activity for an extended period of time,then the device 2800 may transition off to an RRC_Idle state, where itdisconnects from the network and does not perform operations such aschannel quality feedback, handover, etc. The device 2800 goes into avery low power state and it performs paging where again it periodicallywakes up to listen to the network and then powers down again. The device2800 may not receive data in this state, in order to receive data, itcan transition back to RRC_Connected state.

An additional power saving mode may allow a device to be unavailable tothe network for periods longer than a paging interval (ranging fromseconds to a few hours). During this time, the device is totallyunreachable to the network and may power down completely. Any data sentduring this time incurs a large delay and it is assumed the delay isacceptable.

Each of the processors2804A-2804E may include a memory interface, 2904A-2904E, respectively,to send/receive data to/from the memory 2804G.
